glideclient ClassAd
Jump to:
Frontend Advertisement of Requests
The Frontend creates request Classads for the Factory to submit glideins. In the Frontend configuration, you can either match to all entries or customize the match string to request pilots at specific sites. This match string will use information published in the Factory entry Classads and the user’s job Classads.
- User defined values.
- Users are not supposed to affect how glideins are submitted.
Users can affect where they are submitted when the Frontend configures
match expressions and the user provides supported requirements but this
all takes place in the Frontend. User requirements are not put into the
Frontend request for the Factory to interpret. The only exception is the Project ID.
- GlideinEncParamProjectId = "abcx123"
- Users are not supposed to affect how glideins are submitted.
Users can affect where they are submitted when the Frontend configures
match expressions and the user provides supported requirements but this
all takes place in the Frontend. User requirements are not put into the
Frontend request for the Factory to interpret. The only exception is the Project ID.
- Information used to identify the ClassAd.
- Values used to manage ClassAds in the Collector. The id is the credential ID in this
ClassAd and is the grid_proxy, public cert, public key, or username, depending on
the authentication method for this entry. Each request ClassAd contains one set of credentials.
- Name = "id_entry@glidein_name@factory_name @frontend_name.group_name"
- Internal ClassAd type of Master
- Values used to distinguish the different ClassAd types
- GlideinMyType = "glideclient"
- Values set by GlideinWMS for consistency but are not used
- MyType = "glideclient"
- Values used to manage ClassAds in the Collector. The id is the credential ID in this
ClassAd and is the grid_proxy, public cert, public key, or username, depending on
the authentication method for this entry. Each request ClassAd contains one set of credentials.
- Information about the configuration and installation. This is used by admins for
querying the collector or possibly in match expressions.
- These describe the frontend and group making the request.
- ClientName = "frontend_name.group_name"
- FrontendName = "frontend_name"
- GroupName = "group_name"
- GlideinWMSVersion = "glideinWMS UNKNOWN"
- These describe the frontend and group making the request.
- Information specific to a request.
- Information on the numbers related to how many glideins needed.
- ReqIdleGlideins = 0
- ReqMaxGlideins = 1
- The entry that the Frontend needs glideins from. This value is used to match the request to the entry
so it must exactly match the "Name" attribute in the entry ClassAd.
- ReqGlidein = "entry_name@glidein_name@factory_name"
- Information on the numbers related to how many glideins needed.
- Encryption information. The Factory and Frontend use these to identify and talk with each other.
- The Factory Key ID must match the one published by the Factory.
- ReqPubKeyID = "03910dfe2d1101f80fd4f7c388fd2e1c"
- Encrypted symmetric key.
- ReqPubKeyCode = "03910dfe2d1101f80fd4f7c388fd2e1c"
- The Factory Key ID must match the one published by the Factory.
- Security Credentials. All glideins are submitted with some kind of credentials. The Factory
Entry specifies what credentials are needed in the authentication method and the Frontend passes the required info in the
request. Only one (set) of credentials is allowed in a request. All proxy information is prefaced with GlideinEncParam and
the values are encrypted with the symmetric key. The identifier for a given credential does not change between requests (it
is a hash based on filename and not the contents of the credentials).
- Authentication method contains "grid_proxy"
- GlideinEncParamSubmitProxy = ID
- Authentication method contains "cert_pair"
- GlideinEncParamPublicCert = ID
- GlideinEncParamPrivateCert = ID
- GlideinEncParamGlideinProxy = ID
- Authentication method contains "key_pair"
- GlideinEncParamPublicKey = ID
- GlideinEncParamPrivateKey = ID
- GlideinEncParamGlideinProxy = ID
- Authentication method contains "username_password"
- GlideinEncParamUsername = ID
- GlideinEncParamPassword = ID
- GlideinEncParamGlideinProxy = ID
- Authentication method contains "grid_proxy"
- Identity Credentials. The Factory may also require the Frontend to
pass identity information in addition to the authenication methods for glidein submission.
- Authentication method contains "+project_id". This is only applied for TeraGrid sites.
- GlideinEncParamProjectId = encrypted project id
- Authentication method contains "+vm_id". This is used on cloud sites.
- GlideinEncParamVMId = encrypted VM id
- Authentication method contains "+vm_type". This is used on cloud sites.
- GlideinEncParamVMType = encrypted VM type
- Authentication method contains "+voms_attr"
- The Frontend must validate that the submit or glidein proxy contains the VOMS extension. No additional parameter is passed.
- Authentication method contains "+project_id". This is only applied for TeraGrid sites.
- Security Information. The Factory needs additional security information to
make sure the request is allowed. These values are encrypted using the symmetric key.
- Encrypted identity information.
- ReqEncIdentity =<EMAIL_ADDRESS>- The Factory uses the security name for whitelisting Frontends in an entry. The security class must be
agreed upon with the Factory to ensure the correct security mappings exist. If this is not correct, the
Frontend request will be denied.
- GlideinEncParamSecurityName = "frontend_name"
- GlideinEncParamSecurityClass = "frontend"
- Encrypted identity information.
- Frontend defined information for affecting glideins.
- Optional Frontend Admin defined variables. They will be prefaced with GlideinParam.
- GlideinParamUSE_MATCH_AUTH = "True"
- GlideinParamGLIDEIN_Entry_Start = "True"
- Etc.
- The Frontend specifies what Collector the glideins will report to and is required. This value is passed
through to the glideins and is not used by the Factory.
- GlideinParamGLIDEIN_Collector = "collectornode.domain.name:9618"
- The Frontend specifies the web staging area where the glideins will download Frontend provided files.
A descript file (and signature for verification) is used to point to the files and their signs that will be
used in starting the glideins. A Frontend can also contain groups with additional information so both the
Frontend and group descript files are specified. Refer to here
for the structure of the web area on the Frontend as well as the type and format of files expected.
- WebURL = "http:⁄⁄frontend.domain.name⁄path-to-staging-area⁄stage⁄frontend_name"
- WebSignType = "sha1"
- WebDescriptFile = "description.abtfgq.cfg"
- WebDescriptSign = "15af90be49a498528828d321f91ca2302"
- WebGroupURL = "http:⁄⁄cms- frontend.domain.name⁄path-to-staging-area⁄stage⁄frontend_name⁄group_name"
- WebGroupDescriptFile = "description.abtfgq.cfg"
- WebGroupDescriptSign = "b7fde1fd2bc02b02dafd85a655c93f090cfa1e51"
- Optional Frontend Admin defined variables. They will be prefaced with GlideinParam.
- Monitoring and debugging values.
- These are generated by the Frontend and used for generating the monitoring data. All are prefaced with GlideinMonitor. Monitoring values may be shared
between services but are only used in generating monitoring data and not to affect glidein requests.
- Any Classad variable that begins with GlideinMonitor: GlideinMonitorRunning = 0, GlideinMonitorGlideinsIdle = 0, etc.
- This not used by the Factory but in VO Frontends, where it is used for monitoring and debugging.
- ReqName = "entry_name@glidein_name@factory_name"
- These are generated by the Frontend and used for generating the monitoring data. All are prefaced with GlideinMonitor. Monitoring values may be shared
between services but are only used in generating monitoring data and not to affect glidein requests.

Elektra
0.8.14
|
This plugin is an implementation of a parser and generator of the /etc/fstab file.
(Deprecated, remove this section after it is reimplemented in the new way)
For each device in fstab elektra will store the following keys: pseudoname/device pseudoname/mpoint pseudoname/type pseudoname/options pseudoname/dumpfreq pseudoname/passno
Each represents a column in fstab.
The pseudoname can be any name for setting keys, the will be generated when getting keys, so don't expect the same name.
the directory / will be called rootfs
all swap devices will be called swapXX with a number from 00 on for XX
otherwise the mountpoint without the '/' character will be used.
At the other point there is the issue with the pseudonames, you can't rely on the pseudoname you have set.
The biggest issue is that you can't change or delete existing entries. All entries you set will be appended to the other filesystems.
So if you get the filesystems and change the type of the filesystem of the rootfs and set it again the resulting fstab will be like: /dev/sda6 / ext3>-— >-—defaults,errors=remount-ro 0 1 /dev/sda6 / jfs>-— >-—defaults,errors=remount-ro 0 1
which will be not like you desired!
setmntent is used, so it is only conforming to BSD 4.3 and linux and you can't use any comments.
Specification:
[/_] type = array explanation = the name of the key is the mountpoint (so the former mpoint is not needed); the value is the number of entries in the array [/_/#] explanation = an entry in the array [/_/#/device] [/_/#/type] [/_/#/options] [/_/#/dumpfreq] [/_/#/passno]
Example: A fstab that looks like:
/dev/sr0 /media/cdrom udf,iso9660 user,noauto 0 0
would have a key name that is an array (so the value is the number of children, in this case 1):
system/filesystems/\/media\/cdrom
with the array entry:
system/filesystems/\/media\/cdrom0/#0/
So when following line is added
/dev/sr0 /media/cdrom ramfs user,noauto 0 0
Implementation hint: use keyAddBaseName() to get escaping of /, then add array items below it
If a mount point exists more than once (that could be proc, swap or overlay mountpoints) the array below gets incremented (otherwise #0 is used for every unique entry).
The order of the array must, of course, be preserved. Other lines may be reordered for now, a proper "order" could be done later.
Spaces in the names are replaced by \040 in the fstab.
Mount the plugin:
kdb mount /etc/fstab system/filesystems fstab struct type path
The status of this plugin is experimental.

"The ability to monitor one’s own and other’s feelings and emotions, to discriminate among them and to use this information to guide one’s thinking and actions” Salovey and Mayer 1990
Basically as the quote above explains, Emotional Intelligence (EI) is the understanding of ones self emotions and feeling as well as others. This makes it possible to guide how one acts, behaves and thinks in different situations that best suits
Whilst IQ is purely about how smart one is based on their Intelligence, EI is how much one understands emotions and feelings, their intelligence in regards to human emotions.
When working in a group environment it is important to have a good understanding of how you are feeling as well as those around you. If you are able to adapt your emotions to best suit the circumstances it will be much easier to achieve ones goal.

SWORDFISH A film review by Steve Rhodes Copyright 2001 Steve Rhodes RATING (0 TO ****): ***
Okay, admit it. Sometimes movies are so awful, so over-the-top ridiculous that they're good and a lot of fun to laugh at. SWORDFISH, directed by Dominic Sena (GONE IN 60 SECONDS) and starring John Travolta, is one such film. And unlike Travolta's magnum opus of badness, BATTLEFIELD EARTH, SWORDFISH has so few pretensions that it invites you to laugh along with the script rather like the bouncing ball of music sing-alongs.
Since the film's buzz has stemmed mainly from Halle Berry's infamous naked breast scene, perhaps I should start with the warning that the scene is about as exciting as a naked bust in an art museum. She shows them off briefly and rather nonchalantly as she reads. A later scene in which she is in bra and panties, however, will not disappoint those who take in the movie solely for the titillation factor.
The story opens with a long, awkward monologue by Gabriel Shear (Travolta) about the movies. During his soliloquy the camera goes in and out of focus so many times that your head will feel like it may explode. Speaking of explosions, things that go boom in SWORDFISH don't just ignite, they go close to thermonuclear.
SWORDFISH is the sort of movie that relishes its glorification of stupidity. As a hostage wired with remote control bombs walks around, mad bomber Gabriel warns the police to stay away. The agent in charge, A.D. Roberts (Don Cheadle), orders the cops to do what the bomber with the finger on the remote control says. Do they? Of course, not. They give the hostage the biggest bear hug this side of a therapy support group.
 "He lives in a world beyond your world," we are told. "What others only fantasize about, he does."
Gabriel pays way more than minimum wage to the hackers that he uses to crack the world's electronic banking systems. Stanley Jobson (Hugh Jackman, X-MEN), whom the FBI labeled as the most dangerous hacker in America, is brought in by Gabriel for the ultimate test, cracking super secure government computers while having oral sex. Stan, who has a gun to his head, must do this, or he will be gone in 60 seconds. Of course, having been named Wired Magazine's "Man Of The Year" in 1996, Stan finishes just in time.
The script by Skip Woods is quite educational. We learn that 128-bit encryption is pretty secure stuff unless someone with Stan's skills, who kind of intuits his ways through the decoding, is trying to break it. But, 512-bit is really tough stuff. And nobody is up to 1024-bit. Are you taking notes?
You've probably always wondered exactly how superstar programmers work. Well, SWORDFISH shows that to do world-class hacking, you need nine monitors. Standing like a rock musician playing a keyboard, Stan, a triple espresso man, bounces around while writing his code, which appears on multiple screens as both lines of text and spinning 3D models.
In a movie this silly, it's hard to pick a favorite moment. For me, it occurs after Gabriel stands up in his fast, expensive sports convertible to simultaneously shoot down sleek, black sport-utes on both sides.  Others, however, may prefer the film's way, way over-the-top finale. Actually, the more I think about it, the story's ludicrous big secret may be the biggest hoot of all.
SWORDFISH runs a fast 1:37. It is rated R for violence, language and some sexuality/nudity and would be acceptable for most teenagers.
The film opens nationwide in the United States on Friday, June 8, 2001. In the Silicon Valley, it will be showing at the AMC and the Century theaters.

{% blocktrans trimmed %} In this experiment, you take part in a resource allocation exercise. In groups of {{ players_per_group }} participants, you are to submit preferences over a selection of resources. You can be allocated to a maximum of {{ s_len }} resources. You can choose over {{ nr_courses }} resources in total. Also, each resource has a different capacity of participants. {% endblocktrans %}
{% blocktrans trimmed %} Every available resource is linked to a potential payoff. These payoffs can vary within the group.

Frost), Liv Tyler (Grace Stamper), Steve Buscemi (Rockhound), Will Patton (Charles `Chickie' Chapple), William Fichtner (Colonel Willie Sharp), Ken Hudson Campbell (Max Lennert), Michael Duncan (Jayotis `Bear' Kurleenbear), Peter Stormare (Lev Andropov), Keith David (General Kimsey), Owen Wilson (Oscar Choi), Jason Isaacs (Ronald Quincy), Jessica Steen (Jennifer Watts)
Plot: When an asteroid the size of Texas is discovered nearing Earth, it capable of obliterating all life on the planet if it hits, NASA's only hope to save the world is to recruit a team of hard-headed, anti-authoritarian oil riggers to go up into orbit, land on the asteroid and drill to its core to plant and detonate a nuclear weapon to divert its path.
In the same way 1997 was dominated by twin volcano disaster movies (`Dante's Peak', `Volcano'), so 1998 is dominated by twin astral body collision disaster movies with both `Deep Impact' and `Armageddon' vying for our attentions. Despite the commonality of themes, both are quite different films - `Deep Impact' was a tepid soap opera melodrama about how people meet the end, while `Armageddon' is an out-and-out action film. A likely comparison might be between `Saving Private Ryan' and `The Dirty Dozen' - while both are essentially World War II mission movies they are told with quite opposing emphases.
`Armageddon' comes with an absolute determination to be as BIG as it possibly can. It has a reported budget of $272 million which, if accurate, makes it second only to `Titanic' in size. Perhaps the most amusing thing about the budget is that the film's advertizing campaign was almost as large as the actual production budget of the film itself. One certainly can't deny that it has been effective. One has been bombarded by the film's quite nifty promotional campaign for months - giant digital displays in theatre foyers counting down the days, minutes and seconds until the film's opening; posters featuring the faces of the principal characters plastered around the city - "He's doing it for heroism", "She's doing it for love". If only then there had been a film that had been worth such epical effort. Unlike `Titanic', which contradicted accusations of gross over-spending and turned it around to become the success story of 1997, `Armageddon' emerges as only a spectacular monument to its own self-promotion and self-importance over the provision of anything of substance.
Director Michael Bay's previous films - `Bad Boys' (1995) and `The Rock' (1996) - have been filled with gratuitous action sequences and `Armageddon' represents Bay's excesses at their most extravagantly empty-headed. The film is conceived around the provision of a series of dramatic peaks every ten minutes or so. But all Bay seems capable of doing is substituting rapid editing, explosions, flashing lights, people yelling orders at each other all at once, and a dramatically hyping musical score for any real sense of drama. Each action sequence - the destruction of Mir, the landing, the liftoff, the buggy jump, the meteor shower - is just so brainlessly empty in its absurdly over-hyped dramatic contrivations and so unbelieivable as realistic drama that, contrary to what Bay is hoping to achieve, you just sit allowing all the sound and fury to wash over you without even the remotest sense of connection. The writing is absurdly one-dimensional - Steve Buscemi has no purpose in the film other than to crack wry one-liners and Liv Tyler is there it seems simply because the film needs a female lead. It is hard to believe that the nuclear detonation sequence can with complete seriousness offer up such old hat bomb detonation cliches as people yelling "The red or the blue wire ?" and the digital countdown stopping three seconds before detonation. And despite the presensce of at least three scientific advisors on the credits, the film is scientifically preposterous - in a vacuum space shuttles conduct aerial turns like jet fighters; atmospheric turbulence is encountered on a slingshot around The Moon; gravity is inexplicably on while aboard the asteroid and Mir but off back aboard the shuttles; and there is a really, really ridiculous sequence where people are able to turn an extra-vehicular buggy into a flying vehicle simply by turning its gravitic stabilizers off.
It has been a long time since one has seen a film which so relentlessly celebrates its own brainlessness. It wants to be a film about heroism. Heroism here is represented by Real Men - their sweat, their stubble, their muscular brawn, the handsomeness of their faces is shot in emphatic highlight. It is clear that these are Real Men because they do Real Men things like ride bikes, fast cars and horses, gamble, have tattoos, party in stripper bars and above all never give up on a job. But all the heroism comes absurdly posed. The sweat and the stubble on the heroes all comes like it is shot for some fashion layout. The film wants to convince us of some triumph of working class ordinariness but the sheer everyman quality of its heroes is shot in such a way that it attracts attention to the very artificiality of the attempt to do so.
And what the film ends up celebrating is not so much a sense of heroism as an adolescent anti-authoritism. I would be greatly concerned if the fate of the world rested on a group of roughnecks who, among other things, start firing at each other with shotguns when they are annoyed; someone who keeps protesting "She didn't tell me her age, I swear"; and someone who explains their failure at psychological tests on the grounds they were dumped on their head as a child. Everybody on the opposite side of the coin to the heroes is characterized as double-dealing military or ineffectual because they haven't done any `real' work. In its opening moments the film celebrates a scene where the hero fires golfballs at a circling Greenpeace ship while one of his offsiders asks "What's wrong with drilling for oil ?" While one may not always agree with Greenpeace's methodology, the film's mindless celebration of environmental plundering on the grounds that it is a test of real men's courage and the characterization of protestors as worthy of contempt is something that verges on intolerance. Similarly the film gets a big joke out of putting its heroes in a position when they can give the finger to the government and demand they never pay taxes again - but when you see that all the men seem to do with their money is to blow it gambling and in stripper bars, you are struck less by the film's sense of the triumph of heroic take-no-shit individualism than you are by its sense of macho self-centeredness.
And it doesn't just stop there. It is not merely the mindless machimo of the heroism that sticks in one's craw, it is the mindless patriotism of it too. One cannot remember seeing a film before which featured so many shots of people posing in front of the American flag. Like `Independance Day' before it, this is less a film about combatting a world-threatening menace than it is a triumphal assertion of a belief in American identity and individuality. It is not merely a film about Real Men who never give up on a job going into space to save the world, it is about Real Men going to boldly assert their idea of what America is all about. All the heroic posing comes intercut with weightedly symbolic shots of the American flag and cutaways to the Iwo Jima statue and the plaques commemorating the sacrifices of the Apollo mission. And the background is filled with incredibly sentimentalized and equally posed Norman Rockwell-esque shots of good ordinary folk gathered around haybarns listening to the radio or emerging from churches in slow motion. As a non-American I kind of find the cultural imperialism of it all rather hard to take. Most unbelievable of all is the moment the American President goes on air to announce the launch of the mission and people the world over sit and listen in reverential awe, masses of Indians even sit in front of the Taj Mahal in prayer. Give me a break ! All of this in itself may have been slightly more palatable had not the heroic spirit of American independance that we are being asked to cheer on not been one that is so sophomoric and adolescent.

A knot.
A knot is defined as embedding of the circle \(\mathbb{S}^1\) in the 3-dimensional sphere \(\mathbb{S}^3\), considered up to ambient isotopy. They represent the physical idea of a knotted rope, but with the particularity that the rope is closed. That is, the ends of the rope are joined.

); ifTrue
, attempt a faster calculation by using the inverse of the braid
ALGORITHM:
The algorithm used is described in [HL2018] for the corresponding braid representation. We follow their notation, but work in a suitable free algebra over a Laurent polynomial ring in one variable to simplify bookkeeping.
EXAMPLES:
sage: W = Knots() sage: K = W.from_dowker_code([-4,-6,-2]) sage: K.colored_jones_polynomial(2) -q^-4 + q^-3 + q^-1 sage: K.colored_jones_polynomial(2, 't') -t^-4 + t^-3 + t^-1 sage: R.<t> = LaurentPolynomialRing(ZZ) sage: K.colored_jones_polynomial(2, -t) -t^-4 - t^-3 - t^-1 sage: R.<t> = ZZ[] sage: K.colored_jones_polynomial(2, t+1) (t^3 + 3*t^2 + 4*t + 1)/(t^4 + 4*t^3 + 6*t^2 + 4*t + 1)

REFERENCES:
- dt_code()#
Return the DT code of
self
.ALGORITHM:
The DT code is generated by the following way:
Start moving along the knot, as we encounter the crossings we start numbering them, so every crossing has two numbers assigned to it once we have traced the entire knot. Now we take the even number associated with every crossing.
The following sign convention is to be followed:
Take the even number with a negative sign if it is an overcrossing that we are encountering.
OUTPUT: DT code representation of the knot

The set for all knots, as a monoid for the connected sum.
- an_element()#
Return the trefoil knot.
EXAMPLES:
sage: Knots().an_element() Knot represented by 3 crossings
- from_dowker_code(code)#
Build a knot from a Dowker-Thistlethwaite code.
The Dowker-Thistlethwaite code of a knot diagram is defined as follows.
Start following the knot diagram at some regular point. Label the crossings by a number (starting from number 1) in the order in which they are met. At the end, every crossing gets numbered twice, once by an even number and once by an odd number. When meeting an over-crossing with even number, use instead the negative of this even number as label.
Then the set of crossings gives a set of pairs (odd, even). Sort this set according to the odd component, and then keep only the even components in the same order. This is the Dowker-Thistlethwaite code.
INPUT:
a list of signed even numbers, the Dowker-Thistlethwaite code of a knot
OUTPUT:
a knot
Warning
In general the Dowker-Thistlethwaite code does not describe a knot uniquely. It is not only insensitive on mirror images, but may also mix up non prime knots. For example
[4, 6, 2, 10, 12, 8]
describes the connected sum of two trefoil knots, as well as the connected sum of a trefoil with its mirror (see the corresponding example in the documentation ofconnected_sum()
).EXAMPLES:
sage: W = Knots() sage: K1 = W.from_dowker_code([8,10,2,12,4,6]) sage: K1.dowker_notation() [(5, 2), (9, 4), (11, 6), (1, 8), (3, 10), (7, 12)] sage: W.from_dowker_code([6,10,14,12,16,2,18,4,8]) Knot represented by 9 crossings sage: W.from_dowker_code([4,8,10,-14,2,-16,-18,-6,-12]) Knot represented by 9 crossings sage: K3 = W.from_dowker_code([6,-12,2,8,-4,-10]); K3 Knot represented by 6 crossings sage: K3.dowker_notation() [(5, 2), (4, 9), (1, 6), (7, 8), (10, 11), (12, 3)]

A combination of national, state, and local rules guide the redistricting process. While the federal requirements apply universally, state and local governments can establish additional constraints and priorities.
The rules are complicated and sometimes quite vague! Here is a short explainer.
| Population balance: Districts should have very close to the same population | Voting Rights Act compliance: Districts cannot block minority groups from electing candidates of choice |
| Communities of Interest: Groups with significant shared interests should be kept together | Contiguity: Each district should be one connected piece | ||
| Compactness: District shapes should be “reasonable” | Boundary preservation: District lines should follow natural and official boundaries, such as rivers or town and county borders |
For a slightly more detailed discussion, here’s a handout. MGGG collaborator Justin Levitt maintains a guide to state-by-state rules at All About Redistricting. The Brennan Center also has an excellent Citizens Guide to Redistricting, summarized in their 50 State handout.

Disease Outbreak Reported
PRESS RELEASE ISSUED BY WHO
16 OCTOBER 2000
FIRST OUTBREAK OF EBOLA CONFIRMED IN UGANDA
WHO COORDINATES INTERNATIONAL RESPONSE
The World Health Organization (WHO), at the request of the Ugandan Ministry of Health and in conjunction with its partners in the Global Outbreak Alert and Response Network*, is coordinating the international response to an outbreak of haemorrhagic fever in Gulu District, northern Uganda.
Laboratory testing carried out at the National Institute of Virology in South Africa indicates that the cause of the outbreak is the Ebola virus. These are the first cases of Ebola ever reported in Uganda.
As of 16 October 2000, 71 suspected cases, including 35 deaths, have been reported. Cases were first reported in a local hospital in Gulu town and are now occurring in the community.
The Ugandan Ministry of Health has established a National Task Force for the Control of Viral Haemorrhagic Fevers, for managing the response to the epidemic. WHO is supporting the Ministry of Health and this Task Force in disease containment by:
Epidemiologists from the WHO African Regional Office and the WHO office in Kampala, Uganda are already assisting with investigation and implementation of control measures. Drs Mike Ryan and Simon Mardel, epidemiologists from WHO headquarters in Geneva, will leave for Uganda today in order to provide further expertise in clinical management of cases and field investigation of the outbreak.
"WHO and its partners will work with the Ugandan authorities to contain the disease in the outbreak zone and to reduce its spread in local communities," Dr Ryan said. "It is very important that there is effective coordination of the international response to this outbreak."
Initial funding for this rapid response has been provided by the governments of Germany, Ireland, Italy, and Japan.
Ebola haemorrhagic fever is one of the most virulent viral diseases known to humankind, causing death in 50-90% of cases. The Ebola virus is transmitted by direct contact with the blood, secretions, organs or semen of infected persons. The Ebola virus was first identified in 1976 in the western equatorial province of Sudan and in the nearby region of Yambuku, northern Democratic Republic of the Congo, (then Zaire.)
_______________
* The Global Outbreak Alert and Response Network is a technical partnership of national and international institutions and smaller networks who mobilize and pool their resources so that outbreaks of potential international importance are detected, verified and responded to efficiently and effectively by the international community.
